JOHN FEORST, OF BAYONNE, NEWV JERSEY.

HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 426,371, dated April 22, 1890.

Application filed ruary 20, 1890. $e1ia1 No. 341,115. (No model.)

I the county of Hudson and State of New Jersey, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention appertains to that class of devices employed in injecting a spray of inflammable liquid into a boiler-furnace or other combustion-chamber by the action of a steam-jet.

The improvements will be readily understood from the following description, taken in connection with the accompanying drawing, which represents a longitudinal central section of my burner.

In the drawing, the letter A designates a tube, which is provided with an air-inlet a, a steam-supp1y pipe I), and a feed-pipe 0, through which the hydrocarbon liquid is introduced.

13 is a nozzle, which is movably fitted upon the tube A, said tube being provided at its front end with an enlargement d, which forms a guide for the nozzle, and on the body of said tube is a male screw-thread e, which engages a screw-thread f in the nozzle. On the nozzle near its rear end is firmly mounted a hand-wheel C, so that by means of this handwheel the nozzle 13 can be turned and caused to move backward or forward, according to the direction in which the hand-wheel is turned. The rear end of the nozzleB is closed by a packing g, which is held in place by a nut 71. In the discharge-opening of the nozzle is secured a bushing z', of refractory material, which is capable of withstanding the heat to which it is exposed when the burner is in use.

Between the front end of the tube A and discharge-opening of the nozzle B is formed ,a chamber 7', which may be termed amixingchamber, and in which the steam, the hydrocarbon liquid, and the air admitted to the tube A become mixed before they reach the discharge-opening.

D is the regulating-nozzle,which covers and surrounds the nozzle 13, and is held. in position by guide pins or screws 7t 7t and by the tubular extension Z, which is closed bya packing-ring m, held in position by a nut n. The discharge-opening of this regulating-nozzle is provided with a removable bushing o, and from the rear portion of said nozzle extends a pipe 1), through which steam or air under pressure is introduced. By this action of the steam admitted through the pipe 21 the mixture of air, steam, and oil formed in the tube A is blown out with great force, and if said mixture is injected a very powerful flame is produced. The power of this flame is increased when the nozzle B is moved backward and decreased when said nozzle is moved forward.

That I claim as new, and desire to secure by Letters Patent, is-

The combination, with the tube A, having an air-inlet a, the steam-inlet b, and an oilinlet 0, of the nozzle B, adj ustably fitted upon the tube A, forming the mixing-chamber j between the mouth of the tubeA and the nozzle B,the regulating-nozzle D, fitted upon the nozzle B, and the pipe p, connected to the nozzle D, substantially as shown and described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
